Embodiment Construction

[0029] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] Such as figure 1 As shown, the underground coal mine coal field is divided into several mining areas, and the return air lane, belt transportation lane, and rail transportation lane in the mining area are developed to form the ventilation and transportation system of the mining area;

[0031] Excavate the upper roadway, the lower roadway and the cutout along the direction of the coal seam to form an independent return air system. Install a belt conveyor 11 and a scraper transfer machine 12 in the lower roadway, and form a tra...

Abstract

The invention belongs to the technical field of coal seam mining devices, and particularly relates to a thin and extremely thin coal seam mining method and device. An underground mine coal field is divided into a plurality of mining areas, air return roadways, belt conveyance roadways and track conveyance roadways in the mining areas are developed, and ventilation and conveyance systems of the mining areas are constituted; upper roadways and lower roadways and open-off cuts are driven along the coal seam direction, and independent return air systems are constituted; belt conveyors and scraperreversed loaders are installed in the lower roadways, coal conveyor systems are formed through milling coal holes in working faces and belt conveyors in the mining areas, and self-moving air bag supports are installed in the open-off cuts; and coal is ploughed through coal ploughs, and the ploughed coal is transported into the down trough scraper reversed loaders. Equipment operators all work in well-supported roadways without entering the working faces. The self-moving air bag supports are adopted to support roofs, and the coal ploughs move back and forth in the working faces to complete themining process of cutting, loading, transporting, supporting and treatment, thus 0.4-0.8 ultra-thin coal seam working face unmanned mining is realized.

Description

technical field [0001] The invention belongs to the technical field of coal seam mining, and in particular relates to a thin and extremely thin coal seam mining method and device. Background technique [0002] my country's thin and extremely thin coal seam resources are widely distributed and have abundant reserves. At present, the proven recoverable reserves of thin and extremely thin coal seams in the country account for about 19% of the total recoverable reserves of coal. [0003] The realization of automated mining with fewer people and no one is a hot research topic in the current international mining community. On December 19, 2011, Chongqing Energy Investment Co., Ltd. filed an application for an invention patent (application publication number CN102434153A) for a coal mining device and coal mining method for an unmanned working face in a steeply inclined extremely thin coal seam. Although the application for the invention patent The unmanned working face mining of ...
